Major Features

• Lets developers add zip and unzip capabilities to any Silverlight 2 application, quickly and easily. Compresses and uncompresses files without resorting to intermediate disk/memory storage or temporary files, making it the perfect match for Silverlight: it needs no local write access.
• The product's main ZipWriter and ZipReader classes use any seekable or non-seekable Stream-based object as the target or source Zip archive, respectively, for complete flexibility and “on-the-fly” compression/decompression.
• Lightweight libraries.
• Compression starts as soon as data has been received: no waiting for all of the files, or even for complete files. Doesn’t need to know in advance the number or size of files.
• Transfer of the Zip archive over a network can begin immediately, and the remainder of the archive becomes available as it is compressed.
• Secure: Because no temporary files are used while creating a Zip file, there is less chance of unauthorized access or modification of files during the Zip creation process
• Archived files are extracted and available instantly for further processing even if the component is still receiving the Zip archive.
• The size or number of files in a Zip archive has absolutely no impact on memory and disk-space requirements.
• Just a few methods and properties are needed to perform powerful Zip compression/extraction.
• Supports the BZip2, BWT, Deflate, and Deflate64™ compression algorithms.
• AES encryption and decryption are supported for maximum WinZip compatibility.
• Events and properties to monitor and control the Zip writing/reading processes are also provided.
• Reads the Xceed Unicode Extra Header, so it can now preserve filenames with Unicode characters. Very useful for handling international characters.
• Works seamlessly with Xceed Upload for Silverlight.
